Subject: [PATCH v2 00/10] iio: light: veml6030: fix issues and add support
 for veml6035

This series updates the driver for the veml6030 ALS and adds support for
the veml6035, which shares most of its functionality with the former.

The most relevant updates for the veml6030 are the resolution correction
to meet the datasheet update that took place with Rev 1.7, 28-Nov-2023,
a fix to avoid a segmentation fault when reading the
in_illuminance_period_available attribute, and the removal of the
processed value for the WHITE channel, as it uses the ALS resolution.

Vishay does not host the Product Information Notification where the
resolution correction was introduced, but it can still be found
online[1], and the corrected value is the one listed on the latest
version of the datasheet[2] (Rev. 1.7, 28-Nov-2023) and application
note[3] (Rev. 17-Jan-2024).

Changes in v2:
- Rebase to iio/testing, dropping applied patches [1/7], [4/7].
- Drop [3/7] (applied to iio/fixes-togreg).
- Add patch to use dev_err_probe() in probe error paths.
- Add patch to use read_avail() for available attributes.
- Add patches to use to support a regulator.
- Add patch to ensure that the device is powered off in error paths
  after powering it on.
- Add patch to drop processed values from the WHITE channel.
- Use fsleep() instead of usleep_range() in veml6030_als_pwr_on()
- Link to v1: https://lore.kernel.org/r/20240913-veml6035-v1-0-0b09c0c90418@gmail.com
